CURTAIN -F.ASTENER.

Specification of Letters Patent.

Patented Sept. 19, 1916.

To all whom it may concern:

Be it known that I, ADOLPH C. BECKER, a citizen of the United States,residing at Oakville, in the county of Litchfield and State ofConnecticut, have invented a new, and useful Improvement inCurtain-Fasteners; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this application,and represent, in

Figure l a top or plan view of a curtain fastener constructed inaccordance with my invention. Fig. 2 an underside view. Fig. 3 is a sideview. Fig. 4 an end view. Fig. 5 a longitudinal sectional view. Fig. 6 atransverse sectional view. Fig. 7 a perspective view of the spring stripdetached. Fig. 8 a perspective view of the headed stem, detached.

This invention relates to an improvement in curtain fasteners andparticularly to that type which comprises a base or post with a turnbutton connected-thereto and adapted to be turned at right angles to thepost, the object of the invention being a simple construction andarrangement of parts whereby the button will be held in its locked orunlocked position; and the invention consists in the constructionhereinafter described and particularly recited in the claim.

In carrying out my invention I employ a base or post 9 preferably struckup from sheet metal forming an oval chamber 10 and a flange 11 withperforations 12 through which screws or rivets may extend to secure thepost in position. In the top of the post is a clearance opening 13 forthe screw threaded end of a shank 14 which is provided at its lower endwith a head 15. This head has fiat sides and is located between the ends16 and 17 of a strip 18 of spring sheet metal which is located withinthe chamber 10 and formed with a hole 19 through which the screw stempasses, the

ends of the strip being turned inward at substantially right angles soas to bear on opposlte sides of the head 15 yet adapted to yield as thathead is turned. Between the head and the strip is a coil spring 20.Secured to the threaded stem 14 is a turn-button 21 oval incross-section and correspond mg in dimensions at its base to the upperend of the post 9. After the turn-button has been screwed onto the stemso as to draw the head 15 between the ends 16 and 17 of the spring strip18 and placing the spring 20 under tension, the turn-button is firmlysecured to the stem in any desired manner. As herein shown the button isstruck inward on opposite sides forming indentations 22 and forcing aportion of the metal of the button into the sides of the stem so as toprevent the button from being turned off from the screw when it isturned on the base. These buttons are used in the usual way forfastening curtains which are preferably provided with the usual grometswhich set over the posts 9. When the gromets are in place over the post9, the turn-buttons are given a quarter turn so that the ends of thebutton project beyond the sides of the base or post. The coil spring 20tends to hold the turn-buttons in engagement with the post, and theengagement of the ends 16 and 17 of the flat spring 18 hold the post ineither position in which it may be turned, either to allow the gromet tobe passed over it, or in its turned position to lock the gromet with thepost.

I claim A curtain fastener comprising a chambered post, a flat springstrip located in said chamber and having its ends turned inward, aheaded stem extending upward through the chamber, the said head beinglocated between the ends of the spring strip, a coil spring locatedbetween the head and strip, and a turn-button fixed to the upper end ofthe said stem.
